Well when Nieminen was serving for the match Mitya got a penalty point and was really pissed and argued with the chair umpire...
So the match was over and Mitya was still looking a bit angry.. he refused to shake hands with the chair umpire but then changed his mind. So he went to the umpire offered his hand, the umpire took it and he was kind of trying to pull him out of the chair (not too hard but trying).. Umpire said something like stop it and Mitya stopped but said something to him(looked like swearing..). After that the umpire took the phone and was reporting about it. Maybe he is getting a penalty now?!?
